How to save my tree from dying

Hi everyone,

My pine tree are dying now. I took a picture one month ago and it has brown leaves inside and outside. The picture is attached. Today, one of my tree is totally become brown without any green leaves. Anybody know that is it possible to save my tree back? I watering them every 2 days. What causes the dying and what should I do? Thanks.

What kind of trees are those? Where are you located?

The first step in identifying the problem is properly identifying what kind of tree you have. Once you know what type you have you can search online for common problems. I don't know of a pine with dense needles/foliage all the way to the ground like that. Are they a fir, spruce or maybe even a cedar?

 

Sorry for the confusion. It looks like fir but no needles. I do not have much knowledge to identify the trees. I thought the trees' problems are similar.Do you know what's the common reasons for the trees' leaves become brown/yellow?

Thanks

 

As Dane said, the first step is identifying the trees, as something that affects one tree may not affect another.

 

Do a search for something like "identifying conifers" and many, many websites will pop up that can help you identify what you have. Once you know what kind of tree you have then you can start to figure out the problem.

There are many species specific pests and diseases. Unfortunately there is no treatment for many ailments especially with trees as large as yours. The treatment often is to cut down and burn the affected trees at the first sign of stress to prevent them from spreading to nearby trees.

Until you identify your trees you can go out and look at the trunks. Do you see some holes randomly in the bark? If so that's a good indication of some type boring insect. Don't worry about holes in a line. Those are from birds.

 

I'm 99% sure Dane hit it. What you've got there is a boring beetle infestation. Unfortunately it's a 100% kill rate after infestation. Don't let a landscaper or tree service try to talk you into treatments because they will not work. Usually you'll see the pine start dying from the top down and you'll see it dying from the tips of the branches inwards.

Depending on how you look at it, the boring beetle has a very cool adaptation. Once they start boring and laying eggs in the pine, the pine puts off a distress pheromone that actually attracts the beetle.

Best thing to do is cut the tree down and burn the wood. Don't put it in a wood pile or wait for it to dry, just burn it.

Wish I had better news. Look at your healthy trees and if you see very small holes in the bark, about 1/16" - 1/4", then those are infested too. If that's the case, get rid of them all to prevent surrounding areas from getting hit. You can take an adze or a draw knife and shave the bark and you'll see the larvae trails in the cambium.

Sorry

BTW, those are a type of cedar.
